Title: Film unit with lens
Inventor: KAMATA KAZUO
IPC: G03B17/04
Filed: 1992-06-01
Abstract: PURPOSE:To disable a film unit with a lens to be used again by using a film on a market or the like and to prevent misphotographing caused by the reloading of the film or the use of the film unit over a recycling limit by making the tooth of a sprocket one or more size larger than a normal type sprocket. CONSTITUTION:The teeth of the follower sprocket 34 is integrally molded by making the width thereof about 1.5mm wider than the sprocket for the normal 135 type film. In accordance with it, the film 23 whose perforations 23a having width formed wider corresponding to the tooth width of the sprocket 34 than the normal 135 type film is used. Since the film 23 has the special-sized perforations 23a, it is dedicated for this film unit. Therefore, even when the general 135 type film on a market is loaded, it is not engaged because the teeth 34a of the sprocket 34 are larger than the size of the perforations 23a.
